#1 - As Wendy asked, what size is the reserve?
That's probably the most important question.
Will you be able to safely land that reserve in a small area, under 'less than optimal' conditions?
The main probably isn't too terrible of a canopy for you.
The old advice of 'it's too small for you, but if you just be careful you'll be ok' was truly horrible but lots of people survived it.
They simply didn't encounter a situation that required more skill than they had.
Those that did encounter that sort of situation often got hurt. Or killed.
In your case, it's a bit small. But it's a fairly forgiving planform.
It's not like you're jumping a Diablo at 1.5:1 or an Apache at 1.5 at less than a hundred jumps (I know people that have done that, successfully).
Look at Billvon's "Downsizing Checklist" article (on here in 'safety' I think).
Can you do the things on it?
How are your landings under what you are jumping now?
What are you jumping now?
What do the folks that run your DZ think of this idea?
(Hint: If they are saying not to and you're coming here to get approval, don't)
I don't need the answers to these questions.
But you do.
